We have obtained unique gene expression patterns from colorectal cancer and normal tissue by using a newly developed compact-sized DNA array filter system. Collecting, storing, and analyzing of gene expression data from many samples of colorectal cancer will enable us to identify distinct subsets of patients based on molecular characteristics in the near future.

Postoperative outcomes were similar for both valves. An early hemodynamic advantage for the Trifecta valve lasted to approximately 1 year postoperatively but did not persist.

Two months after lung resection surgery, patients had not recovered to the preoperative PAL. However, compared with the control group, there was an improvement in the postoperative PAL in patients, including older patients, who underwent outpatient pulmonary rehabilitation.

Background:In patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS), a sigmoid septum, characterized by subaortic interventricular hypertrophy, often results in the need for new pacemaker implantation (PMI). In this study, we reviewed the feasibility and treatment efficacy of TAVR for AS in patients with a sigmoid septum. Methods and Results:Between 2011 and 2016, 48 patients (25.4%; mean age 84.9±5.4 years; 9 males) with a sigmoid septum and 141 (74.6%; mean age 82.9±5.5 years; 61 males) without underwent TAVR. Their operative outcomes, echocardiographic and electrocardiographic findings, and long-term outcomes were retrospectively compared. Second TAVR because of valve malposition was performed in 3 patients with a sigmoid septum (6.3%) and in 2 patients without a sigmoid septum (1.4%), with no significant difference between the 2 groups. Although there was no significant difference in valve hemodynamics between the 2 groups, sigmoid septum and deep implantation (implantation depth ≥10 mm) were independent predictors of new PMI following TAVR. Conclusions:Although a sigmoid septum did not preclude the feasibility, safety, or efficacy of TAVR for severe AS, its presence was associated with new PMI. Our approach to TAVR in patients with a sigmoid septum may contribute to clinical outcomes comparable to those of patients without this pathology.

OBJECTIVES Fulminant myocarditis with cardiogenic shock requires extracorporeal life support (ECLS) and has poor outcomes. To improve outcomes, we have converted patients with severely impaired cardiac and multiorgan function from peripheral to central ECLS. In this study, we reviewed these patients’ clinical outcomes and investigated associated factors. METHODS We retrospectively studied 70 consecutive patients with fulminant myocarditis under peripheral support from 2006 to 2020. Forty-eight patients underwent surgical conversion to central support, and the remaining patients continued peripheral support. The end point was survival and ventricular assist device-free survival. RESULTS More severe pulmonary congestion and multiorgan failure were present in patients with central than peripheral support. Weaning from ECLS was achieved in 95% and 62% of patients with peripheral and central support, respectively. Five-year survival was not significantly different between patients with central and peripheral support (71.2% vs 87.5%, respectively; P = 0.15). However, the ventricular assist device-free survival rate was significantly higher in patients with central than peripheral support (82.2% vs 52.0%, respectively; P = 0.017). A peak creatine kinase-MB level of >180 IU/l, rhythm disturbance and aortic valve closure were detrimental to functional recovery in patients with central support. CONCLUSIONS Conversion to central ECLS is feasible and safe in patients with fulminant myocarditis. Patients with severe myocardial injury as shown by a high creatine kinase-MB level, rhythm disturbance and aortic valve closure should be converted to a durable left ventricular assist device.
